A great reason to update your phone contacts will be the addition of the new (628) area code in Marin County for new customers beginning March, 2015. Existing (415) area code customers will not be required to change their area code or phone number. However, starting in February, local callers will need to dial full 11 digit phone numbers (1 plus 10 digit phone number), even 415 customers dialing within the 415 area code.
Beginning February 21, 11 digit dialing will be required. Starting now, while it’s still optional, please get in the habit of dialing 1 plus the 10 digit number for all 415 area code calls.
Remember: when in doubt, dial it out (1 plus area code and number) for all 415 calls.
